In the following the state of the art of foldable umbrellas with additional additional functionality such as umbrella sheath with umbrella grip and support of the telescopic tube is appreciated; According to the state of the art - after application reference - a variety of types of foldable umbrellas with additional additional functionality such as umbrella sheath with umbrella handle known.

The Austrian Utility Model AT 006 249 introduces a mini-pocket umbrella, which is pulled to close in the umbrella handle as a hollow body by means of a guided in the middle linkage, the opening and closing mechanism of the canopy string and can be transported in jackets and trouser pockets due to its small volume. This pocket umbrella is ultralight and extremely small. The main screen linkage and the linkage of the roof structure are telescopic. After use, the umbrella is pulled by means of the cord into the umbrella handle and sealed with the lid watertight. Disadvantages of the inventive novelty is that the main linkage is einpunktgelagert in the foot of the umbrella handle and a used wet screen is pulled into the tight-fitting umbrella handle and that the technical solution still needs a certain maturity.

The German utility model DE 20 2007 012 276 / international registration WO 2009/039939 provides a foldable screen with additional additional functionality such as screen cover - in particular a compact pocket umbrella with handle cover and support of the telescopic tube. The preferably oval-shaped handle cover is designed so that it can completely absorb the screen consisting essentially of stand, telescopic tube, slide, roof linkage and clothing by folding and pushing together. About a readily accessible preferably also oval-shaped pull handle, which is finally firmly connected to the telescopic tube, a quick handling by the user is given. The support element provides stability through its tripod design and its tripod slide bearing in any position of the extended telescopic tube of the assembly. Due to the two-sided opening of the handle cover of the screen on the top and bottom - on the head side by the resulting circumferential slot between Griffhüllenkragen and pull handle and bottom side through narrow longitudinal slots in the preferably slightly outwardly curved bottom plate - is a ventilation of the roof linkage and the fabric filled interior is given and an accumulation of moisture is prevented.
The production of the handle cover in its oval shape, the embossed handle shell and the molded collar is relatively expensive and also makes an oval-shaped pull handle required; In addition, the bottom-side ventilation slots are to be considered. The support element must be performed as a tripod due to the selected spatial geometries.

The German disclosure DE 195 25 409 discloses a lockable and lockable preferably cylindrical plastic box as a screen cover, preferably designed for two-wheelers and in particular for the vibration-free and thus silent transport of the folded pocket umbrella. The folded, the umbrella roof forming fabric cohesive rigid cylinder box is closed on one side by a circular bottom and has on the other side a removable lid which is connected to a rack and inserted and thus the clamp-like frame fasteners holding a number / combination lock is locked.
A special feature of the folding umbrella is that it must be smaller than the closed box in its longitudinal extent including umbrella handle.

The German patent DE 195 05 707 relates to a retractable umbrella, the fabric of which is supported by star-shaped around the umbrella pole around roof poles. The roof poles are hinged to a movable along the umbrella pole and lockable at the upper end crown and are supported in the unfolded state of the screen of struts, which are hinged at one end to the roof bars and at the other end to a slider, which also can be moved and locked along the umbrella pole. The umbrella is closed and shortened by folding the roof poles over the crown and inserting the umbrella pole between the collapsed roof poles.
The peculiarity of the arrangement is that the roof bars and the support struts are folded away from the user.

The German patent application DE 102 53 797 presents a screen container with a drying function, the use of which is provided in the motor vehicle, wherein the screen receiving container is in communication with the interior heating of the vehicle or has its own heating with adjustable drying phase. The preferably hollow cylinder-shaped umbrella container should accommodate on the one hand a preferably collapsible dry screen or on the other hand a wet screen pushed together for the purpose of drying. By means of radially inwardly pointing guide ribs form between the cylindrical shell of the container and the inserted screen channels, which are ventilated by fed against the screen entry side air and to dissipate the moisture wet umbrella fabric. Instead of longitudinal guide webs also transverse webs are provided with lateral air supply alternatively.
No statements have been made about the dimensioning of the inventive novelty with respect to climatic conditions.

The German disclosure describes under DE 102 17 280 a multifunctional umbrella and handle holder of a collapsible umbrella. The handle holder comprises a cylindrical pipe section with extending on the inner wall in the axial direction guides for the protection against twisting the length of the folded screen receptacle, at the roof crown facing pipe opening a einstükkig einstükkig connected to the pipe section connecting ring, at the opposite end of a cylindrical cylindrical fixed floor cover and a lower main rod end firmly with this acted hollow cylindrical connector. At the location of the axial guides connecting ring and cover have lateral recesses, so that the connector can be fitted flush with attached on its outer side groove-forming projections except in the axial guide both in the connecting ring and in the bottom cover. Furthermore, the connector has elastic snap elements, which engage in both holes in the connecting ring with the screen open and in similar holes in the bottom cover with folded screen latching. Connecting ring and bottom cover so far form stops for the travel of the sliding in the pipe section connector in the handling of the screen.
When open umbrella linkage, the main linkage is connected via the connector, the connecting ring and the pipe section as a handle holder with this secured against rotation; a second support bearing for the main linkage is not provided.

The European application EP 495 472 / German utility model DE 91 15 108 and DE 91 00 505 present a container with an externally accessible integrated pocket umbrella. The innovative novelty. See a flat container tube in the lid of a briefcase with a small footprint and installed behind the interior. In the cuboid tube, a flat rectangular, telescopic folding umbrella is releasably inserted. The handle of the umbrella is held in place by a lock in the tube; after releasing the lock, the screen is released by a introduced into the central rod of the screen spring mechanism to the outside. Shade and container are only partially - by their design - interdependent.

The German disclosure DE 43 14 650 sees a portable container with a shaped receptacle for additional accommodation of a pocket umbrella. In order to make all three items such as liner-shaped receptacle, screen and / or container when not in use as small as possible and easy to carry and plug in with you, but on the other hand again just in case of need for use just as ready to use in the hand It is proposed that the container be in the form of a roll-up carrier bag or backpack with a liner-shaped receptacle at one end transverse to the side edges of the carrier bag or backpack.
In the present application, the folding umbrella and the container are two independent devices.

The German disclosure DE 40 08 212 is concerned with a Taschenfaltschirm with a umbrella cover, a in the open state the Schirmbespannung spanning, collapsible frame and a handle with the particularity that the frame of an extendable rod - telescopic rod - spiral wires for tensioning the umbrella fabric and the handle of a tubular sleeve for receiving of the central bar, the spiral wires and the screen covering. At the outer edge of the umbrella covering the spiral wires are guided by limiting tension threads, which - together with the spiral wires - end in a manual winding device at the foot of the female sleeve. By operating the rewinding device, spiral wires and drawstrings - including umbrella cover and telescopic rod - are drawn into the female sleeve.
About the dimensioning of the receiving sleeve no indications are made.

The German disclosure DE 23 07 706 / Italian registration IT 20 898 presents a pocket umbrella of any kind - such as folding, telescoping and / or Storchenschnabelschirm - with an attached shell either for receiving the screen in the folded state or as a handle cover when the screen is stretched. The handle cover must be able to absorb forces in the grip area, but may otherwise be made of other, such as compliant or collapsible or otherwise deformable material. Provided is one of the main link crown farthest bottom closure of the hollow cylindrical handle cover, which receives over a clamping the lowest portion of the cross-sectional polygonal pipe boom against rotation. A guide leaf moving along with the main slide to the upper edge of the handle envelope runs in diametrically arranged internal rails of the handle housing.
The guide sheet is rigidly guided within the handle shell by the polygonal tubular pipe and the side rails and tends to tilt at the slightest irregularities of the linkage; a twisting of the screen is excluded.

The German patent, DE 21 37 261 discloses a shortenable screen of collapsed flat cross-sectional shape, at its two wings head having eight telescoping roof rails are articulated in slots, each emerge two roof bars on the transverse sides of the head piece, and at its also two wings having auxiliary slide in an analogous manner the auxiliary struts in Slits are hinged, which auxiliary struts are connected at the other end hinged to the main slide main struts.
A container for the shortenable screen is not provided.

According to the German patent application DE 18 14 204 a pocket umbrella is presented with a shortenable handle and stiffened by star-shaped ribs screen surface, the ribs of flexible, sealed at the ends of tubes and the inner ends open in a central, formed by an upper and a lower wall chamber, the having a slidable air inlet valve and that the multi-part umbrella pole is bolted to the air inlet valve.
An umbrella container is not presented; the size of the collapsed screen is determined by the largest part length of the Schirmstocks.

The German patent DE 62 57 83 introduces a strutless screen, the umbrella pole and Schirmdachungsgestänge telescopic and can be inserted into the umbrella handle, the trigger for the umbrella rod and the guide rings for the rod are also housed in the umbrella handle. Both the collapsed umbrella pole and the collapsed roof bars of roofing roof frame are arranged in the handle housing, that above the closed bottom of the handle housing are each a fixed and a rotatably or slidably mounted circular plate, which can accommodate the ends of the roof bars by frusto-conical axial bores and during the closing process - initiated by a center pin of the main rod - the slidably mounted plate for locking the roof bars. To open the umbrella first umbrella and roof rods are telescoped and last Axialbewegung the center pin pulled from its anchor, which then releases the locking device for the roof rod ends.
The hollow cylindrical umbrella handle consists of a number of guide sleeves corresponding to the roof bars for receiving the same and a centrally mounted guide cylinder for receiving the main boom. The covering for the roofing is designed to be removable and must be stored outside the umbrella handle housing - even when wet. The shield closes tightly in the inserted state and is in the extended state two-point bearings; an internal ventilation of the umbrella handle is not given.

The German patent DE 61 81 74 has a shortenable, completely in the umbrella handle retractable folding screen with two-point, fixed and radialgelagertem main linkage, wherein in a first state two - from below slipped - integrally screwed sleeve halves of different diameters form the hollow umbrella handle and in a second, the sleeve halves against each other hollow body forming screwed and the rod and the string receiving state are closed. In the closed bottom of the smaller-diameter sleeve half a guide rod in the axial and radial directions is rigidly mounted on which a telescoping hollow rod rigidly connected piston slides, which in turn is supported on the inner wall of the first half sleeve and can move from the sleeve bottom to the open sleeve edge and complete it there.
Through the two sleeve halves, a closed hollow body is always formed and sealed in the first state of the sleeve halves slipped over by the piston, so that moisture formed by condensation or screen wetness can not be released. The axial extent of the contacting cylindrical surfaces of the sliding piston releases large frictional forces with the sleeve inner wall. The moving, tight piston generates - depending on the direction of movement - inside the sleeve a pressure or a vacuum.

The English registration GB 2 403 904 / Spanish registration ES 2 293 292 / American patent application US 2006 174 928 / international registration WO 2005 013 755 describes an umbrella holder or carrier for receiving a folded umbrella, wherein the holder is provided with fastening or carrying straps, which in turn around or on carrying handles of a piece of luggage - such as bags or suitcases - can be slipped or fastened. The faceplate is substantially pronounced as a hollow cylinder and may also have ventilation openings. The screen carrier according to the invention is presented as a part independent of the screen.

With the english registration GB 2 320 893 a folding and foldable folding umbrella is presented, in which the folded umbrella is completely housed in the umbrella handle. The roof linkage opposite end of the main linkage - the guide linkage - is mounted in one piece in the closed by a cover bottom of the hollow cylindrical handle housing längsachsendrehbar. On the second linkage section of the main linkage - running over the guide linkage - an inner diameter is at its end opposite the roof linkage the handle housing outside diameter-matched slider or support integrally attached and moves when removing the main and roof rods from the umbrella handle from the bottom to the opening of the handle housing and stabilized there as a second bearing the axially rotatable main linkage. The handle housing is slightly frusto-conical open towards the opening to allow easier insertion of the linkage in the handle housing.
The glider or support as a second bearing with extended main and roof poles is already in protective rights publications around 1930 subject of foldable umbrellas.

With the english registration GB 365 954 Such a foldable screen is presented that a well-known umbrella with main and roof linkage, covering and handle in a long, low-diameter, folding and lockable two-shell hollow cylindrical handle housing folded place, the handle protrudes at one end of the housing and the screen crown the opposite end of the folding housing. The umbrella handle is connected by two diametrically opposed narrow guide rails with one half of the folding housing such that when opening the housing opened in half, removed the rail-mounted screen and turned away at right angles from the housing and opened and rotated against the starting position by 180 ° - like at a fair market ship swing - placed again in the half of the housing and closed by the second cover half.
Since the handle housing length corresponds approximately to the length of the umbrella, the non-foldable umbrella is unsuitable as a pocket umbrella.

Also the English patent specification GB 311 265 presents a screen container in conjunction with a lady's handbag so that the screen finds place in designated holders within the purse.

The Japanese patent application JP 2002 291 509 presents a foldable telescoping pocket umbrella with a waterproof case and help to close and open the umbrella. In addition, the screen is a reserve container in case water has collected a wet screen in the housing. In addition, the housing has a screwable discharge opening. Umbrella knob and housing opening are firmly screwed together in the closed state; the screen is removed from the housing for use; The case acts like a packaging. The umbrella pole is firmly connected to the knob.

The Japanese patent application JP 2000 070 024 also introduces a foldable pocket umbrella, which finds its place in the folded state completely in the handle cover. The handle cover is made up of several pieces and consists essentially of two sandwich pipe sections - each consisting of two cylindrical shells, which are resiliently held and closed via elastomer compounds, of which the roof linkage farthest, larger diameter first pipe section has a split bottom cover, the one-sided Angling the half shells is formed. The second smaller diameter also designed pipe section has at its end facing the roof rod end per half-shell a hinged lid lid flap with a central bore which is pronounced towards the hinge edge facing out as a slot, so that the extended main linkage is centered when it is closed lids. The two multi-piece nested and -gleitenden pipe sections are formed in folded umbrella only at its two open ends large volume to an elliptical cylinder connected to each other and are formed when the screen extended an almost volumenhalbierenden hollow circular cylinder forming a handle shell.
Due to the axial and radial volume change in the state change from the handle housing empty housing to the screen receiving transport housing, the housing design designed very expensive. The elliptical, in the radial direction by pressure yielding transport housing halves do not exclude skin lesions at the feed dog.

The Japanese publication JP 5 123 211 presents a foldable umbrella with a handle cover, which is designed in particular for receiving a wet umbrella fabric. The handle cover consists of a cylindrical Rohrrabschniit, the bottom side is bolted to a bottom plate, which is prepared for a hollow cylindrical receptacle for the linkage; the inserted linkage is pegged in the recording non-rotatably. At the opposite upper end of the handle casing has an axially short, wall-reinforced shoulder, which receives an internal thread. The cylindrical canopy is screwed via a floating bearing adapter with the rod and covers folded and inserted screen, the handle cover over a hollow cylindrical shoulder, which has an internal thread of the handle cover matching external thread for the purpose of tight screwing the handle cover, between screen cap and handle cover a sealing o-ring fits. Two gripping nubs arranged on the outside of the lid periphery of the umbrella cap serve for handling the same for screwing on and off.
When unpacking and packing the fine umbrella fabric of the folded, possibly wet screen is pushed over the sharp-edged inner thread-bearing paragraph in the longitudinal direction without rotational movement in the handle shell; Damage to the clothing is specified after repeated use. A second bearing - in addition to the bottom-side bearing of the handle cover - as a support for the linkage at the upper end of the handle cover is not provided.

The American publication US 4,821,756 discloses a collapsible umbrella which, when folded, fits completely within a handle envelope, with the main linkage not telescoping, and the handle shell length being greater than the largest length of roof pole or main linkage. The skin linkage has at its lower, the roof rack opposite end in the interior of the handle cover axially displaceably mounted piston, which forms a guide cylinder for the main linkage. A second guide undergoes the linkage upon exiting the handle cover at its end facing the roof rack. To open the umbrella main and roof poles are pulled as far as the handle cover until the roof bars are no longer covered by this, then the roof rack To open with stringing and the main rod can be pushed back so deep into the handle cover until handle cover and roof rack meet. Main linkage and roof bars are not telescopic, the main linkage is secured against rotation, the shield housing is tightly closed; the length dimension of the umbrella prevents suitability and use for the pocket umbrella.

The American registration US 4,456,023 discloses a foldable screen with telescoping linkage in a solid watertight envelope in which the umbrella tip has a screwable handle cap with which the envelope is sealed when the umbrella is inserted. The solid shell has on the cylindrical inner wall extending in the axial direction grooves in which tongues of the slider of the telescopic rod run against rotation during insertion and removal of the screen. At the upper end of the inner wall, the longitudinal grooves merge into radial helical spiral grooves; Thus, the slider of the extended screen can be locked to the upper shell inner stop by a rotary movement against the shell cover. A dense screen housing forms in the interior climate-related non-draining condensation moisture, as caused by the moisture of a umbrella fabric. This solution also offers only a one-point storage of the extended telescoping linkage at the top of the envelope.

The US Patent Authority has with the publication US 2 091 676 a foldable pocket umbrella protected, the handle housing consists of two in- / übereinander longitudinally displaceably arranged inner sleeve and outer tube halves, the lower bottom of the sleeve is closed and the guide tube of the telescopic umbrella main frame integrally receives and the opposite cover of the tube half through the end cap of the rod roof crown is formed and closes the handle housing in the folded state tight. At the lower end of the first tube after the guide tube a closed circular disc-shaped guide is attached via a collar, which slides with the opening of the screen or the telescopic main linkage to the upper open end of the inner sleeve and this closes in this state on the one hand and on the other hand, the second forms radial support bearing for the main linkage. Two opposing, longitudinally extending on the inner wall of the inner sleeve longitudinal wedges are in accordance with two correspondingly shaped and shaped slots of the guide discs in line and to form a security against rotation between the inner sleeve and the main rod.
The rotation of the shield is given only when the outer handle tube is secured against rotation against the inner sleeve. The closed guide disc - working like a piston - seals against the inner wall of the inner sleeve and can - depending on the direction of movement - in the interior of the sleeve vacuum or pressure builds up. Even a slight deformation of the inner sleeve allows only a limited movement of the guide disc.

In contrast, the American application shows US Pat. No. 1,885,968 a one-point mounting of the main linkage in the screen housing the handle housing by means of a piston having a radially extending over the outer diameter of the same protruding tongue, which in a spiral in the axial direction over the cylindrical Inner wall of the handle housing extending groove slides and thus offset the piston in a rolling motion during axial displacement.
The rolling movement causes a relative movement between the collapsed screen and the inner wall of the handle housing when extending and retracting the screen to safely position the umbrella cover and the frame, with increased friction between the handle housing and piston occurs.

In contrast, the American application shows US 892 813 a one-point support of the main boom in the handle, which is depending on the extent of the screen and position of the linkage in the base or at the top of the container.

Also the American registration US 868,326 shows a foldable umbrella with umbrella container, in which the stability of the main boom is also given only in a Fußpunktlagerung the handle / container.

The international application WO 1997/048303 'Combined Ambrella Case and Handle' introduces a hollow-cylindrical umbrella handle to be screwed with a lid, wherein the cylindrical lid is slotted over a radius mainframe width and the umbrella handle - when filled with a folding screen - is closed by the cover screw and the screwed lid - Condition with extended screen - for the two-point bearing has a passage and a lock for the main linkage. The over the handle cover cantilevered has at its edge an internal thread, which is designed to match the external thread of the handle cover. Furthermore, the lid to the boom outlet through a mouth hole with a protruding collar pronounced over a slotted also on Gestängemaß clamp is slipped, which closes the slot opening by rotation and forms the above-mentioned second camp next to the fixed bearing in the handle cover bottom when Faltschirm extended. Another embodiment describes a fixed rotary valve with a small manually operated handle knob instead of loosely slipped over, turn-mounted rotary clamp. Another embodiment shows a hinged hinged lid hinged to the casing edge, which is held in the closed state by a manually operable latching device. The handle cover has in a first solution an open, in the radial direction bordered bottom, where by means of two body washers fixed to the main rod, or - in a second approach - a closed bottom with a centrally set bolt or dowel over which the main rod is fixed ,
The screw-cap solution with rotary clamp or locking lid with rotary clamp as a solution for the other bearing point for the main rod loses points in the appearance of value - the wide lid slot for the linkage releases a large opening. The main linkage is integrally attached in the bottom of the handle cover.

All publications presented are suitable only partially or not at all for the specific use as a foldable screen with additional additional functionality such as a screen cover - especially not for a compact pocket umbrella with handle cover and supporting a rotatable and lockable double bearing main boom.

The invention is therefore based on the object, a device according to the preamble of claim 1, a foldable screen with additional additional functionality such as a screen cover - especially a compact pocket umbrella with handle cover and support a rotatable and lockable double-mounted main linkage - to create.

This object is achieved by the characterizing features of claim 1; to advantageous embodiments, the dependent claims. The aim is to build a foldable folding umbrella with additional functionality such as a screen cover - especially a compact pocket umbrella with handle cover and support of rotatable and lockable double-bearing main boom. The handle shell preferably shaped as a hollow cylinder is designed so that it can completely accommodate the umbrella consisting essentially of guide tube, support element, main linkage, main and auxiliary slide, roof crown, roof linkage and covering by folding and pushing together. About a well-accessible preferably also disc-shaped pull handle, which is firmly connected to the roof crown and ferrule finally with the main linkage, a quick handling by the user is given.

A further advantageous embodiment of the inventive novelty represents the combination of guide tube, support element, main linkage and main and auxiliary slide in that the support element by its frustoconical design and its tripod slide bearing and suspension in any position of the extended main linkage arrangement stability - but also a certain yield - gives.

A further advantageous embodiment of the invention is given by the fact that by the two-sided opening of the handle cover of the screen on the top and bottom - head side by the circumferential, a ring forming spacers between handle shell collar and pull handle and bottom through narrow slots or holes in the disc-shaped base plate or also by a circumferential, wreath-forming spacer between the handle shell collar and bottom cover - a ventilation of the roof frame and the string filled interior is given and moisture accumulation is prevented.

An approximately similar expression of cover and bottom part on the one hand the inclusion of the roof crown of the main boom on the one hand and the pivot bearing for the guide linkage on the other hand helps to reduce tooling costs and parts count.

The achievable with the present invention consist in particular in the shape of preferably a spatially frustoconical tripod of preferably with the at the lower end of the first pipe section - after the guide tube - the main rod firmly connected support member. On the one hand, the expression of the resilient plain bearing within the handle cover leaves no full cross-sectional area Design of the support element, on the other hand creates the expression of the support element as a tripod clearance for air ducts of the ventilated interior handle cover.

Furthermore, a three-point bearing of the guide tube and main linkage - and thus the screen load - optimally based on the one hand, secured stability and on the other hand minimum friction between the support element and the inner wall of the handle shell during extension and insertion of preferably with the lower end of the first pipe section - after the guide tube - Main linkage firmly connected support element.

Another advantage in the embodiment of the invention lies in the ergonomic and promotional design of the handle cover; the preferably hollow cylindrical design of the aluminum body is the user well in the hand, gives the wearer by the high quality materials a special feel for the value and offers an ideal advertising space even with unopened fabric.

According to another design variant, the torsionally stiff main linkage in conjunction with the guide tube is preferably polygonal and does not allow any rotation in this area.

The guide tube preferably polygonal cross-sectional shape is stable and rotatably connected to the handle cover over a suitably shaped, housed standpipe cone in the form of a movable bearing, but locks in its end position against rotation.

The possibility of rotation when inserting the folded screen in the handle cover provides the screen wearer an advantageous screen insertion aid to even in hurry packaging of guide tube, support element, main and auxiliary slide, roof crown, roof linkage and clothing by folding and pushing together in the handle shell no injury of man and material.

Furthermore, there is a further advantageous embodiment of the invention in the accessibility of the user to the pull handle for the purpose of umbrella opening in that a circumferential, wreath-forming spacer between handle shell collar and handle gr0ßzügig space for manual handling.

The combination of rotatability with extended umbrella rod and non-rotating seat in the inserted state offers advantages for the user or wearer, as in high wind load or when abutting the roof rod tips a freewheel is given on the one hand, thereby avoiding damage to the fabric and / or the guide rod in the fixed bearing and a risk of injury to the wearer is reduced, and on the other hand handle cover and linkage form a compact in itself stable unit.

Significantly, the expression of created for the ventilation and handling lamellae 42 is made , which is integrally connected to the pull handle 41 and the underlying roof crown 43 . The lamellar rim consists of the diameter gleichabständig axially aligned arranged ribs, which are pronounced in two stages in their longitudinal extent. In a first stage, a distance serving as an air gap in the longitudinal direction between the handle shell top edge and the pull handle projection is produced, and further the extent of the ribs in the radial direction corresponds to the inside diameter of the handle wrapper. As a result, m air channels are formed between the ribs and the inner wall of the handle shell with a number of m ribs.

Both openings of the hollow cylindrical handle cover 2 , 21 are capped; the handle cover takes the collapsed guide tubes 1, 2 31 , 32 and pipe sections 1, 2, 3 33 , 34 , 35 of the main linkage 3 with the support member 331 completely. In this state, the support member is held against rotation by the locking pins 62 of the abutment 60 . If the locking pins are designed as latching hooks, the opening of the screen 1 is only forcibly guided. The Fußpunktlager 5 consists of an integrally attached to the hollow body 21 lid 51 , 52 , which in turn is integrally connected to the abutment 60 and between this and the bottom cover, the pivot bearing 55 receives, which by a receptacle 53, a fastening means 54 and a centering 57th is fixed. Pivot bearing and counter bearing have the contact surfaces 58, 61 in common. The guide tube 1 31 of the main linkage 3 is integrally connected to the pivot bearing; since all tubes and sections of the main boom are connected by torsion-resistant tubes, the locking pins of the fixed abutment hold the support element over the radial slot 332 , the support member acts on the tube section 1 on all tubes and sections and the pull handle 41 against rotation and on the guide tubes 1, 2 32, 33 also on the pivot bearing 55. To open the screen, the pull handle must first be pulled axially until the locking pins of the abutment release the radial slots of the support member; then the covered screen can be removed by gently turning / pulling the handle cover. The support member 331 follows in its spatial configuration with the dome 335 the frustoconical structure of the pivot bearing 55 and thrust bearing 60 and thus receives in addition to the necessary compliance the required rigidity.

Fig. 3 shows the compact folding umbrella 1 in the extended state as a partial view and indeed in Fig. 3 a) as a side view and in Fig. 3 b) as a sectional view. The support element 331 closes the roof crown 43 next to the closest opening of the hollow cylinder 21 of the handle cover. 2 The pipe sections 1, 2 33, 34 are non-rotatably connected to the guide tubes 1, 2 31 , 32 and the guide tube 1 via the pin 59 has a fixed connection to the pivot bearing 55 , which can move freely in the shield open state in the abutment 60 , so that external influences on roof linkage 7 (not shown) and umbrella cover 8 (not shown) - such as tearing the screen or strong gusts - have no damaging or destructive effect on this.

Fig. 4 shows the overall view of the folding umbrella 1 in the extended state, in Fig. 4 a) as a side view and in Fig. 4b) Sectional view, and makes the complete structure of the main linkage 3 with guide tubes 1, 2 31 , 32 and pipe sections 1, 2, 3 33 , 34 , 35 clearly.

Fig. 5 specifies the structure of the base point bearing 5 with the support element 331 in an exploded view in FIG Fig. 5 a) in perspective view and in Fig. 5b) as an item-sectional representation. The Fußpunktlager consists essentially of the plastic lid 51 with molded attachment 52 and a receptacle 53rd The lid attachment is dimensioned in diameter so that it is firmly bonded in tight fit in the lower opening of the handle cover 2 , 21 with the same. The plastic lid may be provided for the ventilation of the handle cover with slots or holes 63 or with a lamellar ring formed from single ribs (not shown), as already performed at the top lid opening; In this case, the tabs of the illustrated lid attachment are pronounced in ribs, but lifted from the design of the pull handle 41st Significant for the tightness of the lid is that it can absorb all the forces acting on the screen.

With the lid recording the pivot bearing 55 is in close connection. This plastic part has several functions; it takes over the notched pin 59, the guide tube 1 31 against rotation, with the support 56 , it supports the main linkage 3 rotatably on the bottom cover and forms with the cylindrical surface of the bearing shell 58 the connection to the fixed plastic abutment 60th The anvil is integrally ultrasonically welded or bonded to the bottom cover, wherein the bearing shell 61 previously receives the pivot bearing 55 . Structurally, the counter bearing can be connected via a press fit with the bottom cover and the handle cover. The counter bearing also has molded locking pins 62 , which receive the support member 331 in the retracted state of the pocket umbrella. These locking pins can also be designed as a latching hook with appropriate expression of recordings in the support element, so that for the purpose of opening the screen first via a tensile force unlocking of an abutment and support element via the pull handle 41 takes place before the umbrella parts linkage and stringing perhaps by slight rotation or rolling movement of the handle cover are removed. Also at this point are constructive alternatives attached. The support element bundles over the receptacle 337, the roof rod tips in folded and inserted screen. 1

Fig. 6 shows the support member 331 as a single part, in Fig. 6 a) in plan view, in Fig. 6b) in perspective, in Fig. 6c) in side view and in Fig. 6d) as a sectional view. The support member is mounted at the lower end of the pipe section 1 33 of the main linkage 3 in one piece over the pipe receptacle 336 , moves inside the hollow cylinder 21 of the handle cover 2 between Fußpunktlager 5 with inserted screen and upper handle cover edge with extended screen and forms - in this state - next to the Base point bearing the second support for the main linkage. The body of the support member is substantially frusto-conical shaped as a dome 335 , adapts to the shape of the bearing shell 61 of the thrust bearing 60 , has the edge towards a frustoconical sump 337 , which receives the roof rod tips in folded and inserted screen 1 . The extended in the radial direction edge of the support element is designed multifunctional; the edge is in areas with a 120 ° pitch - as shown - located alternately in a support zone 334, a sliding key 333 and a venting zone 332nd Under the freely chosen 120 ° division - other divisions are also possible - form the support zones a static materialdurchsetztes tripod, which essentially receives the emanating from the covered roof construction transmitted via the main rod radial forces and these and the axial forces together with the Fußpunktlager. 5 on the hollow cylindrical handle cover 2 , 21 transmits. The outer dimensions of the tripod are minimally undersized tolerated over the hollow cylinder inner diameter.

The support zones are followed by a sliding spring and ventilation zone. Due to the undercut of the support element edge, this region acts as a spring element with respect to the inner wall of the hollow cylinder 21 . With slight radial oversize relative to corresponding dimensions of the support zone, the Gleitfederzonen are always on the hollow cylinder inner wall, give the application of radial forces slightly after until the support zone contacts the inner wall. During extension and insertion of the main boom, the springs slide over the hollow cylinder inner wall 21st In the illustrations according to the figures, the undercut of the support element edge is projected as a parallel radial slot; An elliptical, hyperbolic, parabolic or non-parallel undercut can additionally support the spring effect, also depending on the choice of material. But also the two-time truncated cone sequence - Dom 335 and recording 337 - from the tube receiving 336 to the outer diameter of the support element give the support zone in addition the properties of a spring. On the one hand, the expression of the resilient plain bearing 333 within the handle cover 2 does not allow a full cross-sectional design of the support member 331 , on the other hand creates this expression of the support element as a tripod clearance for air ducts 332 for the circulation of the ventilated interior handle cover and ensures the pressure equalization in the process of supporting element ..

Advantageous developments of the invention are the subject of the dependent claims; The numerous possibilities and advantages of the embodiment of the invention are reflected in the number of patent claims.
